Pilomatricoma
or calcifying epithelioma of Malherbe is the commonest hair-follicle tumor
and is frequently seen in children. Clinically, pilomatricoma usually
presents as a firm, deeply seated nodule that is covered by normal skin,
but occasionally it is more superficially located, causing a blue-red
discoloration as like as this case. The face and upper extremities are the
most common sites. Hardness of the tumor is a good clinical clue for
diagnosis.

Histologically, the
tumor is composed of two types of cells, basophilic cells and eosinophilic
(shadow cells). Eosinophilic foci of keratinization and basophilic
deposits of calcifiction are scattered throughout.
